Ive been waiting for quite awhile to buy a spare cat for my Keystone, they've been out of stock for at least a month now. I finally emailed them about it and they said it will be at least another 3 weeks. Seems odd they are taking so long for such an important replacement part right at the start of burning season. Good thing my cat is working fine but I'm going on year 4 and I'd like to have a spare ready to go just in case. I've also noticed other stove cats are out of stock as well.
The IS was backordered last year,I got mine around Christmas. Woodstock was aware of supplier issues and have an eye toward bringing it "in house"
